You install Drill on nodes in the cluster, configure a cluster ID, and add Zookeeper information, as described in the following steps:
- 1. Download the latest version of Apache Drill [here](http://apache.mirrors.hoobly.com/drill/drill-1.11.0/apache-drill-1.11.0.tar.gz) or from the [Apache Drill mirror site](http://www.apache.org/dyn/closer.cgi/drill/drill-1.11.0/apache-drill-1.11.0.tar.gz) with the command appropriate for your system:
- * `wget http://apache.mirrors.hoobly.com/drill/drill-1.11.0/apache-drill-1.11.0.tar.gz`

2. Extract the tarball to the directory of your choice, such as `/opt`:
`tar -xzvf apache-drill-<version>.tar.gz`
3. In `drill-override.conf,` use the Drill `cluster ID`, and provide ZooKeeper host names and port numbers to configure a connection to your ZooKeeper quorum.
